Frequently Asked Questions
Q: What is the difference between the Relay output and SSR output versions of the REX-C100 PID Temperature Controller?
A: The Relay output version uses a mechanical relay to switch your heating or cooling element on and off. It is suitable for lower-frequency switching applications and resistive loads. The SSR (Solid State Relay) output version sends a low-voltage signal (typically 0–5V or 3–32V DC) to trigger an external SSR module, enabling faster, silent, and longer-lasting switching — ideal for higher-cycle or precision-critical applications like sous vide or 3D printing. SSR Output Set 3 includes an SSR module bundled with the controller and K-type probe for a complete, ready-to-use solution.
Q: What is a K-type thermocouple and is it included with the REX-C100?
A: A K-type thermocouple is a widely used temperature sensor made from two dissimilar metal alloys that generate a voltage proportional to temperature. The REX-C100 is designed to accept K-type thermocouple input and can measure temperatures from 0°C to 1300°C. The K-type probe is included in Relay Output Set 2, SSR Output Set 2, and SSR Output Set 3. Sets 1 (Relay and SSR) include the controller unit only, so you would need to source your own probe separately.
Q: How do I install and set up the REX-C100 Digital PID Temperature Controller?
A: The REX-C100 uses a standard 1/16 DIN panel-mount format. Cut a standard panel opening, slide the unit in, and secure it with the provided mounting clips. Connect your thermocouple probe to the input terminals and your heating/cooling load to the output terminals according to the wiring diagram. Power the unit via AC 100–240V. Use the built-in auto-tuning (AT) function to automatically calculate optimal PID parameters for your load — simply set your target temperature, activate AT mode, and the controller does the rest.
Q: Is the REX-C100 suitable for DIY home projects as well as industrial use?
A: Yes. The REX-C100 is popular among both DIY enthusiasts and professionals. Its wide temperature range (0–1300°C), flexible output options, and compact DIN form factor make it suitable for everything from home brewing fermentation chambers and egg incubators to industrial kilns and heat-treatment ovens. Always ensure proper electrical safety precautions are followed during installation.
